Last updated: July 2026 dataPreserved clams, cockles, and ark shells — dried, salted, or held in brine — enter the US under three distinct 10-digit tariff lines: geoduck-excluded dried/salted clams (0307790150), a further carve-out excluding Stinson clams (0307790155), and cockles and ark shells in the same preservation states (0307790160). Canada leads supply, with Vietnam and China also significant sources, reflecting both wild-harvest and aquaculture origins across the Pacific Rim. All shipments are subject to FDA oversight for seafood HACCP compliance, and importers should verify that foreign establishments meet US food-safety equivalency standards. Classification hinges on species identity and preservation method — misidentification between cockles and clams can shift the applicable tariff line.

The schedule separates geoduck-excluded dried/salted clams (0307790150) from a subset that also excludes Stinson clams (0307790155), and places cockles and ark shells in their own line (0307790160). Correct classification requires confirming both species identity and the specific preservation method — dried, salted, or in brine.
FDA requires importers to have a seafood HACCP plan and to verify that foreign suppliers operate under equivalent hazard-analysis controls. Shipments from Vietnam and China may be subject to enhanced FDA import scrutiny, including prior notice filing and, in some cases, automatic detention orders for specific product categories. Consulting a licensed customs broker and reviewing current FDA import alerts before shipment is strongly advised.
